2. Description of the Related Art Conventionally, glass decorations have been used for metal gates, windows, fences, and signboards, but the present applicant has first made a decoration using glass used for these. A method of manufacturing the arranged decorative structure was proposed (Japanese Patent Publication No. 6-60551).

In this method, a decorative body is formed by holding an outer portion of a glass body with a lead or lead alloy casting. Of the decorative structure such as a gate, a part other than the decorative body is cast with an aluminum alloy, and both are fixed with screws or caulked. Further, a metal piece that can be soldered may be inserted so as to protrude at a position corresponding to a contact portion with the decorative body during casting, and the decorative body may be fixed by soldering to the protruding end of the metal piece. .

[0004] Thereby, glass can be easily arranged on a decorative structure such as a metal gate.

[0005]

However, according to the above-mentioned manufacturing method, the portion for forming the glass decorative body includes:
A cast of lead or lead alloy had to be used, and a glass cast had to be soldered to a cast part of aluminum alloy. This is because the melting temperature of the aluminum alloy is as high as 680 ° C. and the glass body is damaged during casting.

Therefore, there has been a problem that the weight of the decorative structure increases due to the lead portion, and the fixing work as described above increases.

In view of the above problems, the present invention provides a glass decorative body in which a portion for holding glass can be formed of an aluminum alloy.

[0008]

According to a first aspect of the present invention, there is provided a glass decorative body in which a plurality of outer portions of a glass body such as a sphere, a plate, and a three-dimensional shape are substantially point-contacted with an aluminum alloy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment FIG. 1 shows a decorative body 10 according to a first embodiment. The decorative body 10 is used for a gate.

At the center of the decorative body 10, a substantially rectangular glass plate 12 is provided. The decorative portion 14 holding the glass plate 12 and having a decorative effect is made of an aluminum alloy.

Usually, the glass plate 12 is damaged near 680 ° C., which is the melting temperature of the aluminum alloy. In this embodiment, in order to prevent this damage, the decorative portion 14 made of the aluminum alloy and the glass plate 12 are damaged. , That is, the holding portion 16 is provided so as to be substantially in point contact with the four points of the glass plate 12. The glass plate 12 is held by the four holding portions 16 and casting is performed only by contacting this portion, so that the glass plate 12 is not damaged during casting.

Unlike the conventional case, the glass plate 12
And the decorative part 14 made of an aluminum alloy are integrally cast,
The decorative body 10 can be configured.

In this casting method, a glass body is provided between a pair of sand molds for casting, and a molten aluminum alloy is poured into the glass body for casting. At this time, the contact portion between the glass plate 12 and the molten aluminum alloy is only the holding portion 16 as described above, so that the glass plate 12 is not damaged.

(Second Embodiment) FIG. 2 is a front view of a decorative body 20 according to a second embodiment. The decorative body 20 is a hanging member for hanging the signboard 22.

The decorative body 20 includes a decorative portion 24 made of an aluminum alloy, a plurality of glass balls 26, and a glass plate 28.
Are integrally cast.

As described above, the glass may be damaged by the melting temperature of aluminum, but the glass ball 26 has high durability, so that only a part of the glass ball 26 is used as in the first embodiment. It is not necessary to adopt a configuration that makes contact with the aluminum alloy casting, and the casting may be performed so as to cover the entire glass ball 26.

Further, the glass plate 28 is made of tempered glass and has higher durability than ordinary glass, so that the glass plate 28 is not damaged even if its outer portion is surrounded by an aluminum alloy. However, since there is a difference between the coefficient of thermal expansion of the tempered glass and the coefficient of thermal expansion of the aluminum alloy, in order to allow this difference in thermal expansion, a part of the portion surrounding the glass 30 is provided. Thus, even if the external temperature changes and the decorative portion 24 made of an aluminum alloy thermally expands, the glass plate 28 is not adversely affected.

The gap 30 may be provided at a plurality of places depending on the size and shape of the glass plate 28. In this case, since the position corresponding to the gap 30 becomes a protrusion in the sand mold, the protrusion serves to fix the glass plate 28 when the glass plate 28 is stored in the sand mold.

FIG. 3 shows a modification of the second embodiment, in which only the tip of the decorative body 20 is formed separately. In this case, as shown in FIG.
Screws are insert cast. On the other hand, this tip 32
A female screw portion to which the screw 34 is screwed is attached to a portion to which is attached.

FIG.

The decorative body 100 has a spherical glass ball 10.
2 is supported by a pair of metal support members 104, 104, and the pair of support members 104, 104 are held by aluminum castings 106, 106.

The material of the pair of support members 104, 104 may be the same aluminum, or a metal having low thermal conductivity and heat resistance.

As a method of manufacturing the decorative body 100, the glass ball 102 is held by a pair of support members 104, 104, and the integrated body is placed on a mold of an aluminum casting 106. Then, an aluminum casting 106 is cast by pouring aluminum into this mold.

In this manufacturing process, even if aluminum is cast, the glass ball 102 does not come into direct contact with the high-heat aluminum, so that the glass ball 102 is not damaged by heat.

[0036] FIG. 10 is a modification of Reference Example, the ginseng
The difference from the example is that a glass plate 108 is used instead of the glass ball 102 and four support members 104 are used. In this case, the support member 104 is
Is formed to be slightly larger than the thickness of the glass plate 108 so as to sandwich the glass plate 108.

Even with this method, the glass plate 108 can be easily formed.
